Multiple measures of vowel overlap have been proposed that use F1, F2, and duration to calculate the degree of overlap between vowel categories. The present study assesses four of these measures: the spectral overlap assessment metric [SOAM; Wassink (2006). J. Acoust. Soc. Am. 119(4), 2334–2350],...

Although most auditory lexical decision experiments are performed in a laboratory setting, humans tend to communicate in uncontrolled and noisy environments. We investigated, indirectly, the impact of noise and other distractions on lexical processing. The present study used a subset of words...

Measuring the dispersion of density in head and neck cancer patients' vowel spaces: The vowel dispersion index

Matthew C. Kelley, Daniel Aalto
The present study introduces a measure of the dispersion of density throughout the vowel space, which we refer to as the vowel dispersion index. The vowel dispersion index is based on calculating the total variation of the density values in Story & Bunton’s (2017) convex hull representation of...

Pseudowords are used as stimuli in many psycholinguistic experiments yet they, remain largely under-researched. To better understand the cognitive processing of pseudowords, we analysed the pseudoword responses in the Massive Auditory Lexical Decision megastudy data set. Linguistic...

Using phonological neighborhood density has been a common method to quantify lexical competition. It is useful and convenient but has shortcomings that are worth reconsidering. The present study quantifies the effects of lexical competition during spoken word recognition using acoustic distance...
